ELECTRIC-CONDUIT FITTING.

Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed February 11, 1910. Serial No. 543,310.

To all whom it may concern Be it known that I,-CARL H. BISSELL, of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Electric-Conduit Fitting, of which the following is a specification.

My invention has for its object the production of an electric conduit fitting adapted to inclose electrical appliances such as fuse-blocks, etc., and has for its object the production of means for securely and conveniently supporting such appliances and facilitating their removal and replacement and their ready connection to the electric wires in the conduits; and it consists in the combinations and structures hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a plan of my conduit fitting,

the cover being illustrated in open position. Fig. 2 is a longitudinal sectional view of such fitting showing an electrical appliance, as a fuse block, mounted on the support therefor. Fig. 3 is an isometric view of the support. Fig. 4 is an enlarged sectional view illustrating the catch and contiguous parts.

1 is the body or box of my electric conduit fitting, such box being here shown as oblong and as having one longitudinal side open and provided with a closure 2. The body or box 1 is provided with one or more means as outwardly projecting nipples 3, 4 for connection with suitable conduits 5, 6 inclosing wires 7. The nipples 3 and 4 project laterally from angularly arranged sides of the body or'box 1 with longitudinal portions thereof'in the same general plane as the side 8 of the box opposed to the closure 2, and. preferably, the bases of the nipples 3 are formed funnel-shaped for facilitating deflecting of the wires passing through such nipples to the electrical appliance within the body or box. I havej'here shown the body or box 1 as provided with two nipples 3 and two nipples 4, but it is obvious that the body or box may be provided' with any desirable number of nipples for connection to electric conduits, and that instead of said nipples, any other suitable means may be The closure 2 is preferably connected to the body or box 1 at one longitudinal side by hinges 9 and is provided at its opposite side with means for securing the same to the body or box, such means being here illustrated as a spring-pressed sliding catch 10 mounted on the inner face of the closure 2, and provided with a finger piece 11 projecting through the closure beyond the outer face thereof, and also provided with an engaging portion 12 coacting with a shoulder on the interior of the body or box 1. It will be understood, however, that the sliding catch 10 forms no feature of my present invention.

13 is a support detachably mounted within the body or box 1 and adapted to carry an electrical appliance, as a fuse block 14, said support being provided with a number of lengthwise slots 15 for receiving suitable means, as bolts or screws, for securing the electrical appliance to the support. Preferably, the support 13 is of less width and length than the opening controlled by the closure 2 and is detachably secured within the body or box, thus permitting ready removal and replacement of the support and the electrical appliance carried thereby, and further, the support is spaced apart from the opposing side 8 of the body or box 1, and the axes of the nipples 3, 4, thus permitting the passage of wires between the support and the side 8, and end edges of the support are spaced apart from the opposing sides of the body or box 1 for permitting the electric wires to be passed between said end edges and the opposing sides of the box from the nipples to the electrical appliance, one end of the support 13 being preferably provided with a cutout 16 for facilitating the passage of wires to the appliance 14.

In the illustrated. construction of my invention, the side 8 of the box is provided at one end with a. pair of lugs or projections 17 arranged on opposite sides of the longitudinal intermediate portion of the box and is provided at its opposite end with a similarly arranged pair of lugs or projections 18 of less height-than the lugs or projections 17, said lugs or projections 17, 18 having surfaces 19 20 thereof opposed to the sides 21 of the box inclined relatively to said sides 21, and to the general plane of the support 13, and Eric of said sides 21 is provided with a pair of lugs or projections 22 provided with hook-shaped extensions 23 projecting toward the side 8 of the body or box- 1, and having angularly arrange surfaces coacting with the upper cinls air inclined surfaces 19 of the lugs or projections 17 surfaces of the extensi ns 23 being parallel to the surfaces 19. and the other end of said support is provided with extensions 24 at opposite sides of the cutout 16, which extend in the same general plane as the main pcrtion cf the support and between the wall 8 and the lugs or projections 22, and are provided with surfaces parallel with and coacting with the opposing surfaces of said projections. In placing the support 13 in position it is arranged in the b dv or box 1 substantially parallel to the side 8 with the extensions 23 to the right of the lugs or projections 17 and is then moved rectilinearly endwise, thus engaging the extensions 23 with the-inclined surfaces 19 of the lugs or projections 17 and moving the extensions 24 beneath the lugs or projections 22.

The support 13 is provided with looking members 25 which preferably extend through the extensions 24 of .said support, and coact with the inclined surfaces 20 of the lugs or projections 18. As the members or screws 25 are moved longitudinally toward the wall 8. or in a direction at an an-- gle to the rectilinear movement of the support 13 into and out of engagement with the lugs or projections 17, 18, said members or screws 25 coact with the inclined surfaces 20 of the lugs or projections 18 and move the support 13 endwise to the left and firmly .hold the support in position, with one side s in the reverse direction, the support 13 may be readily detached from the lugs coacting with the extensions 23 and 24 of such support, whereupon the support and the appliance carried thereby may be easily removed from the body or box 1.
